GAR BOLSTER.

Specification of Letters Patent. Patented plfll, 1922.

Application filed November 28, 1919. v Serial No. 341,002..

To @ZZ whom it may concern:

Beit known that I, vWILLIAM J. TANGER- MAN, a citizen of the United States, and a resident of Hammond, Lake County, ln

diana, have invented a certainnew, useful, and improved Car Bolster, oit' which .the

following isa specification.

My invention relates generally to improvements in railroadcar Vholsters but recan be produced from materials of standardl forms or construction obtainable in the open market. i Y

It is'also an object orn my invention to provide a method of producing body bolsters in less time, with less material, atless cost and of greater strength, for the metal em- Aployed, than `is obtained in methods of pioduction heretofore used; and itis also an .object of my invention to provide a method of producing body bolsterswhereby standard rolled sheetsand shapes may be utilized thus making available a constant supply .ot materials .at relativelylow cost.

My invention consists generally in the form, arrangement, construction and o o-operation of theA parts; and .in the steps, acts,

andfsequencethereo followed in the manu- .,facture of the'bolsters, whereby theabove named objects, together with others that will appear hereinafter, are attainable, andlmy invention will be more readily understood by referenceto 'the accompanying drawings 'which illustratevwhat l consider, at the pres-y ent time, to be thebest embodiment thereof.

, In said drawings'i Y Fig l is a perspective viewior'fa channel or the bolster `is member from which part constructed.

Y HFig. 2, is a Yperspective `view of ,another lchannel. member rromwhlch another part ofthe bolsterisigconstructed.

Fig. 4, `is a side elevation ofthe channel member of Fig. 2 cut into twopai'ts.

Fig. 5, is a perspective view of a portion tion 5. and

or the channel which is removedifor use in Vanother vpart or the bolster.

Fig. 6, isa kperspective view of one end portion oit theainderframeof a car provided with a body bolster embodying my invenrig. 7, is a' end portions or the bolster some of the parts being broken away better to disclose the interior construction.

Fig. 8, is a'detail view. substantially on the line 8 8 of Fig. 6.a i 5 l As stated in the opening ofthe specification itis an object ormy inventionto produce a body bolster, largely rroinistandard .i

roll sections or shapes, and to do so substantially withoutY waste. As a iirst step in the method or manufacture, il selectV a'channel member 2 which`V is a standard rolled section such't'or example, as` a fifteen-inch, thirty-three pound section. The length of Y v perspective view of one or the Y the' channel memberQ is such asto be-substantially twice as long as the desiredchannel section.

As a next step l cut the channel member 2, 'l

into two partsas along the double-curved, dotted line 3, of' Fig. l, thus providing two complementary channel members 4 and 5 which comprise body portions 4. andf respectively and tongue portions 4". and .5V y

respectively. 'The channel member may be cutl or severed in desired or approvedv f manner, asror example, by the `usefo'lian" oxyacetylene or .v other V torch: The tonguel portion it will be noted in' each instance" AVembodies therein oneA of thefflanges andv `a portion or whatis termed the webv or the channel member. Another chan-nel Vmember or' the size of that shown in Fig. l is, proi vided which, however, is cutV along the double ,i

curved 'dotted` line 6 (see Fig. 2) .whichline Vvof severance, is-.reversedwith respect to the line. of .severance shown yin Figs. 4,l and4 3;V

The severed and separated Vchannel members 7 and Sfillustratedf in Fig.; lare thus proy vided.-` VThe channelv members 7 and 8 VVcomprise, respectively, body portions and 8f,

, and tongue portions 77. and 8 The'tongue vportions or the respective channel parts 4, 5,

7 andjS aresevered as along the lines 9,10, 11 and l2, ,v-respectively, thus.,providing a plurality of `small parts 13 or the general form shown in Fig. 5.

The body bolster. asa

Wholeconsists'Y ei,

the channel members 4, 5, 7 and 8, the members 4 and 8 constituting a pair, and the members 5 and 7 constituting a pair. As shown in the perspective view Fig. 6, the parts 4 and 8 are arranged on the near side of the center sill 14, whereas the parts 5 and 7 are on the other side. In positioning the parts the tongue portions 4 and 8 respectively, extend outwardly in a transverse direction from the center :sill 14, whereas the body portions 4 and 8 terminate adjacent the center sill. This positioning ot the parts causes the flange portions ot the channel members to extend in opposite directions or in other words causes the web portions oie the channel members to Jface each other. similar disposition of the channel members f5' and 7 is made upon the far side ot the car.

The respective channel members are held in spaced relation by means of the upper cover plate 15 which extends the full, length of the bolster crossing the center sill and which is secured to the flanges ci the bolster parts 4. 5, 7 and 8 by suitable rivets. The

cover plate 15 is also secured to 'the flanges of the center sill channel members 16 and 17 as by riveting. The center sill channels l16 and 17 are also provided with a cover plate 18 secured by riveting to the flange parts thereof. The bolster parts' 4, 5, 7 and 8 extend a sufficient distance above the level or top of the plate 18 so that the bolster cover plate 15 may rest thereon. i. e. it is in a plane with the top Hang-es ot' the bolster parts. The lower cover plate 19 is also riveted, the bolster parts and lower part of the lcenter sill thereby further assisting in the proper spacing of the bolster parts and very considerably strengthening them. Both the cover `plates 15 and 19 are composed ot standard plate material procurable in the open market.

The various channel members 4, 5, 7 and 8 ot the bolster are further secured to the channel members ot the center sill as by j means of tour angles one of which is shown in Fig. 6, and which bears the reference character 20. Other angles are similarly positioned, i. e. where body portions of the members 4, 5, 7, and 8-meet the center sill. The bolster channel members are additionvally held in proper spaced relation by means ol separators, one ateach end of the bolster,

and which appear in Figs. 6 and 7- bearing the reference character 21. VVThe separator 21V is a channel member which is bent to L- shape, providing the Yvertical portion v21 .and the horizontal portion 21 (see Fig. 7).

`The flange portions 22 and 23 thereof are secured to adjacent parts of the bolster as by means of rivets. The opposite end ot the bolster is provided with a similar separating angle member. These members serve not only as separators but they also lserve lugs for bands or rods which tie the tank to the under frame. For this purpose the hole 25 is provided in the portion 21 of the separator through which the lower end ot the tank band passes. The tie band not being strictly a part of the bolster is shown only by means ot dotted lines in Fig. 7, and bears the reference character, 26.

At times it is desirable to jack up the under trame' and it is convenient to place the jack under the bolster ends. For this reason, 'I provide the angle jacking members 27 which are made by cutting away a part of the member 13 (see Fig. 5) as along the dotted line 28. They are riveted to the separating member.

The tank supports 29 are shown in certain figures oi the drawings, but these will not be described tor the reason that they constitute no part of the present invention and are shown only to indicate the adaptability of the bolster to tank car construction.

Tt is now obvious that in the production of my body bolster practically all ot the met-al selected is utilized. This elimination ot waste reduces very materially the cost ot the bolster.

Again., it will be noted that castings and special shapes heretofore largely utilized in bolster construction have been supplanted by the use of standard shapes and plates which not only greatly reduce the initial cost of the bolster,and simplify its manufacture,

but which also results in a great saving of time when it becomes necessary to repair they car for the reason 'that the repair parts, i. e. the plates and shapes necessary may be obtained from any warehouse. That isto say, it is not necessary to send to the manufacturer or original car builder for the parts, which is necessarily the case where special castings or pressed shapes are used. Thus the repair of the car is simplified and cheapen'ed andundue delay avoided.

One more point should be mentioned and that is that a bolster is subjected to unusually severe strains, due to the rocking of the car,'along those portions joining the vertical and horizontally disposed parts of the bolster. Under prior constructions utilizing channel members tormed of pressed plates,

the flanges of the channelparts were joined to vthe base by a rounded portion which in the tion of the method and the resulting struc- Y ture will be sufficient to teach the advantages to those skilled in the art Without further comment, but inasmuch as this disclosure will also suggest to others, modified structures whereby the substantial objects and purposes of my invention may be attained, l do not wish to'be limited to the specific construction herein shown and described, nor to the precise steps of the method, nor tothe stated sequence thereof, except only as may be necessary by appended claims.

-v claim:

1. A body bolster plurality of pairs of rolled channel members, one pair arranged on eachside of the car center sills, the webs of the channel members facing each other, and means spacing said members apart and securing them to the center sills. l s

2. A body bolster embodying therein a plurality of pairs of rolled channel mem- 30 bers, one pair arranged on each side of the car limitations in the hereunto embodying therein a center sills, the webs of the channel members facing each other, and means spacing said members apart and securing them to the center sills, one of saidV spacing members being formed and positioned to serve as a Atank band lug. l

3. A car underframe construction having Y sills in combination with a body bolster, said bolster comprisingV two rolled channel members extending from each side of the center sills, separators secured to and holding re-V spective channel members in spaced relation, and means securing said channel members to thek center sills, and top and bottom cover plates secured to the bolster and center sill parts.

4. A car underframe construction havingV v center sills Yin combination with av body bolster comprising spaced channel members secured to the center sill and a top cover plate secured tothe flanges of said channels, said channels` beingL reinforced Where the flange thereofjoins the4 web portion thus adapting the bolster to withstand the severe' strains imposed by rocking movements of the car.

In testimony. whereof, I have hereunto setY myA hand, this 7th day of November, 1919. l
